[SPARK-19021][YARN] Generailize HDFSCredentialProvider to support non HDFS
security filesystems
Change-Id: I85d7963c4980cf9660f495f377ba27227da4b1b1
Currently Spark can only get token renewal interval from security HDFS
(hdfs://), if Spark runs with other security file systems like webHDFS
(webhdfs://), wasb (wasb://), ADLS, it will ignore these tokens and not get
token renewal intervals from these tokens. These will make Spark unable to work
with these security clusters. So instead of only checking HDFS token, we should
generalize to support different DelegationTokenIdentifier.
## How was this patch tested?
Manually verified in security cluster.
